For all you people out there who play blackjack, you may already know what a difficult game it is to master. My belief though is that most people simply do not know about the marvelous subtleties of the game. In fact when I read my first ever blackjack book back in around 1990 then my knowledge and understanding of the game quantum leaped. That book was Beat The Dealer by Ed Thorp which was the first great blackjack book.
The game is deeply mathematical in nature, but yet as someone who is not well grounded in mathematics myself, I know from personal experience that there comes a time when knowing the in depth mathematical stuff using qualifications in highly advanced mathematics and statistics is simply not needed and has diminishing returns. There are far more important skills to playing blackjack and beating the game inside live casinos.
Honesty is a massive element in team play and I do know of certain blackjack teams who used polygraph machines to test to see if results were being reported correctly. I tried to get around this problem by operating in such a way as to make everything as open as possible. I did not allow any team member to operate alone as I knew that this would be a problem or at least a potential problem.
At the end of the day, people need money and people have debts and bills to pay. If they don’t have enough money to get by or if they have other expensive habits then the temptation to steal is ever present. I never wanted to go down the avenue of polygraph testing although at one stage I did secretly inquire about the price of a such a device and how easy it would have been to get hold of one.
But these are things that need to be ironed out first and not during the operation. Also it is pretty difficult to ask someone to take a test when it is them who is stumping up the money as the main financial backer. So I was in a very awkward situation anyway. But polygraph testing has been used numerous times with professional gambling teams and not just in casino blackjack either……and you thought that professional blackjack was all about counting cards 
see you soon
